cons to running a 12" front rim?

[abadsvt]

Hi guys. I am building a 63 vette conv. and having fender flares made for the front and rear which would allow me to tuck a 12" front rim if I wanted. I am running 325's for the rear and for some reason i love the idea of big meaty tires up front also. Providing I had enough clearances is there any cons that I am missing with running that wide of tire up front? Im going crazy trying to decide if I want 10" or 12" front rims! I thought I would get some opinions

Thanks
